Or it's simply not to your taste, but equally that doesn't make it any less worthy, would be an alternative viewpoint.
Personally, I would have angled the knife more to improve composition. Just MHO.
Actually, I do believe you only really know you've done something good when it manages to provoke a bad reaction in a proportion of people. I don't take that kind of thing as an insult -- quite the reverse!
On the composition, I agonised over it for quite a while, but ended up going with what had been in my head in the first place. I got a nicer reflection on the knife blade at that angle, so I just left it be.
I think that this kind of 'creative' work is a lot different to my landscape stuff in concept as well as execution. With landscapes, you basically turn up, pick a location, find the right time, and shoot, but composition is essentially limited to what's there (assuming you're not going to attack the countryside with enormous backhoes or something!). The 'creative' stuff (I hate that term, but it seems to be what people use to describe it in the photography community, so I'm stuck with it, I think) typically starts as an idea, and I then make the whole image *from scratch*, finding or making any necessary props along the way. It's a substantially different approach. Also, I find myself using colour for the creative stuff, and hardly ever for landscapes. Neither of those things seem particularly to be choices, it's just that it seems to work out that way. It seems wrong somehow to call both approaches photography in the strictest sense of the word. The Ashes and Snow site that you linked has some amazing images (it pushes a few too many cliche buttons for me, but it's certainly beautiful work), which clearly fall more into the creative camp than the straight photography camp.
It's a big world. There is room for plenty of approaches. If a whole load of people started copying my style, I'd find that highly entertaining. But then, I don't need to earn a living from photography, so my mileage varies -- I can do whatever I like, and don't particularly need to care whether it caters to a specific (or indeed any) market. Then again, I'm not a one-trick pony, so even if people *did* copy my style, I'd probably be doing something else by then anyway.
More realistically, I think the probability of people even noticing that I, or my photographs, actually exist is so vanishingly small that this is all fantasy anyway. In the mean time, I'm intending to keep having fun clicking those shutters.
